3.0 Science and Data Analysis
3.1 Flight Events and HETG Instrument Status
The HETG continues to function with no outstanding issues.
There were 8 targets observed in 11 observation intervals by the HETGS in March 2002. Four of these targets are in the HETG GTO program and will be examined in detail by the HETG group.
3.2 Guaranteed Time Observer (GTO) Program
Work accomplished
During March, conflicts between the GTO targets and Guest Observer (GO) targets were identified by the CXC. HETG adjusted its GTO program so that 2 targets remain with GO conflicts and will go to the Peer Review in June for a decision. Science backup for these two competed targets was supplied to CXC as required.
Four of our eight Cycle 3 GTO targets were successfully observed in whole or part – See Appendix A, the GTO Observation Status Table for target identification and details.
Progress was made in data analysis and publication preparation for many of the GTO observations; see Appendix A. Results from several of these analyses will be presented at the HEAD meeting, April 20-23, in Albuquerque.
Work planned
Continued analysis, presentation and publication of science results. Specifics on papers written and talks given will be included in future reports.
3.3 Science Support to SWG, CXC, etc.
No major support was provided to the SWG or CXC in this period.
4.1 Documentation
Documents identified and consolidated internally.
4.2 Test Instrumentation and Spares Retest
Work Accomplished
Received turbo pump accessories and installed the
new pump and checked the vacuum system. A leak was found and fixed in the
source area. The new turbo ran fine. The HV supply was also re-installed.
The source station is now up and running.
Started to check out system
operation, found some simple but time consuming “bugs”, e.g., a
wire had shifted and prevented proper homing of motorized stage.
Work Planned
Continue system checkout and run a test sample to validate operation.
4.3 Tests and Anomaly Support
Supported closeout of the limit switch issue.
5.1 Program Office & NASA Support
POP 02 inputs were provided prior to March 1. Supported monthly Chandra telecon.
5.2 MIT-internal management activities
We are pleased to note that Dr. Julia Lee will be leaving her HETG post-doc position this fall as she starts her Chandra fellowship here at MIT. Hiring activities were carried out and an offer was made to a post-doc to continue in Dr. Lee’s current position in the fall.
Created monthly report format/draft. Supported internal office and computer issues.
6.0 Open Issues, Problems, etc.
There are no known critical open issues or problems regarding the HETG.
A request for foreign travel was submitted April 5 for Dr. Lee to attend the Fourth Microquasar Workshop,“Microquasars and Their Relation to Other Relativistic Jet Sources in the Universe” in May 24 – June 3.

Notes:
1. Entries indicating progress during this period are shown in this font.
2. Due to time limitations not all table cells with known information have been filled in – subsequent reports will be more complete.
3. Up-to-date observation information can be obtained from http://cxc.harvard.edu/cda/ using the WebChaSeR link.
